Disclosed is a liquid crystal display (LCD) device capable of enhancing an aperture ratio and a transmittance ratio. The LCD device includes a first substrate and a second substrate; a plurality of gate lines formed on the first substrate, each gate line having a first region and a second region with the width less than that of the first region; a plurality of data lines disposed so as to be perpendicular to the gate lines to define a plurality of pixel regions; a thin film transistor (TFT) formed on the first region of the gate line; a common electrode and a pixel electrode formed on the first substrate, and forming an electric field; a black matrix and a color filter layer formed on the second substrate; and a liquid crystal (LC) layer formed between the first substrate and the second substrate, wherein the first regions and the second regions of the gate lines are alternately disposed in an extending direction of the gate lines and in an extending direction of the data lines, and wherein two TFTs are formed on the first region of the gate line corresponding to the pixel region, two TFTS being respectively connected to pixel electrodes of two pixel regions adjacent to each other based on the gate line.

Liquid crystal display device and method of fabricating thereof

An LCD and a method of manufacturing the same using at most six mask processes are provided. An active layer and a storage electrode are simultaneously formed by diffraction exposure. Multiple ion implantations are performed using a photoresist or the gate electrode to mask different areas of an underlying semiconductor. Source and drain electrodes and a pixel electrode are simultaneously formed by diffraction exposure. First and second connection electrodes that lower the contact resistance between the drain electrode and the active layer are formed by a lift-off process.
